Networking – Is It Possible to Change My MAC Address?

have you ran ifconfig -a ?

ubuntu and debian these days use udev to persistently assign the same nic the same device name. This works great except for when it doesn't do what you want it to do.

justin@media:~$ cat /etc/udev/rules.d/70-persistent-net.rules 
...
# PCI device 0x8086:0x100e (e1000)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:08:74:f2:83:e2", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

if you run that on your VM you will most likely see two lines, one for eth0 and one for eth1. the easy way to fix it is to delete the eth0 line, and change the remaining eth1 to eth0.

It is possible to change the MAC address with the motorola WiMax dongles that use the Motorola Connection manager. There is a hidden menu, and it can be changed in there. I don't remember the exact command to change it, and I don't have the software installed currently, but to access the hidden menu, go to the Profiles menu then hit: Ctrl + Shift + Alt + ~

Also, Intel only makes internal cards. It is not possible(unless you have the development tools, that are only available for intel employees) to change the mac.
